Tangent sells them. http://www.tangentsoft.net/shop/ But he is out of stock until mid June.

With at least 10.3 and 10.4 it is plug and play. Shows up as an additional sound device. Haven't tried it with anything older.

Are you plugging the Cmoy into the amplified output of some pc speakers? Try plugging it directly into your computer's line out. Or better yet a portable CD/mp3 player.

Try replacing R5 with a larger resistor. 10ohms is just a starting point. http://www.tangentsoft.net/audio/cmo...tweaks.html#r5

Try pulling the other electrolytic capacitors. If they were stressed they could be shorting internally. Maybe they weren't sealed good and some alcohol got in there. The output capacitors probably wouldn't have any effect though, if they shorted it wouldn't affect the power supply...

Time to build Alien DAC!

LM833 has bipolar inputs. It will not be stable in a Cmoy circuit without modification. Tangent has an explanation on this: http://www.tangentsoft.net/audio/hs-opamp.html Better to start with something like the recommended OPA2132 which has FET inputs.

Check your output jack wiring. I once had L-L R-G G-R. It played but sounded weird.

The crossfeed's capacitors do not provide any protection. Take a look at the schematic and you will see that the majority of the signal goes straight through R1 and back out.

Have you checked out this thread? http://www.head-fi.org/forums/showthread.php?t=228976 It may be a grounding problem. Looks like you don't have it in a case yet though.

Are you sure it's the adjustable version? Or maybe R31/R32 are swapped. Can you take a picture of it?

Did you install R31/R32? Pins 1/2 are the output pins. Pin 4 is ground. Are you numbering the pins correctly? 5-8 all on one side are tied together and connected to the input voltage.

Check if your meter has a continuity check feature. Use that instead. It will beep when there is a closed circuit. So you don't need to watch the display. Some flux is conductive. You should clean it off before powering the circuit. You are probably dealing with 3 different types of flux...

Some of those solder joints on those socket pins don't look too good. Hard to tell from the pictures but it looks like they could do with a reheating.
